1. A sterile object remains sterile only when touched by another sterile object. Sterile touching sterile remains sterile. Sterile touching clean becomes contaminated.

The edges of a sterile field or container are considered contaminated.     

TYPES OF PAIN  A. Superficial 1. Arises from local tissues 2. Usually related to a nerve ending disturbance 3. Localized; usually described as constant, sharp, tingling or throbbing B. Visceral 1. Arises from somatic structures 2. Deep pain; may be dull or aching C. Referred - Pain felt in another area separate from source of pain D. Central 1. Caused by injury to central nervous system 2. Very intense pain; burning CLASSIFICATIONS OF SURGICAL WOUNDS RELATIVE TO RISK OF INFECTION The higher the class, the higher the risk: a class IV wound carries much more risk than a class I.  A. Class I (clean wound) 1. No break in sterile technique 2. No inflammation encountered 3. GI, Respiratory or GU tract not entered B. Class II (clean-contaminated wound) 1. GI, GU or respiratory tract entered with no spillage of contents 2. Minor breaks in technique 3. Operations involving the biliary tract, appendix, vagina, and oropharynx C. Class III (contaminated wound) 1. Acute inflammation without pus 2. Spillage from a hollow viscus occurs 3. Trauma from a clean source D. Class IV (dirty) 1. Pus or a perforated viscus 2. Trauma from a dirty source 3. Organism causing infection present before surgery 4. Surgical variables that increase risk of infection 5. Prolonged preoperative hospital stay 6. Body location of surgery 7. Surgical technique: delayed wound closure, excess blood loss, presence of drain, improper  suture tension 8. Presence of bacteria at closure

3. Complications a. wound complications i. dehiscence: complete separation of wound edges or  ii. evisceration: wound edges separate; viscera protrude cause: obesity; malnutrition; too much coughing/straining cover with gauze soaked in sterile saline and report immediately keep client in flat position iii. infection b. circulatory complications: thrombosis and embolism c. fluid and electrolyte imbalance d. urinary retention i. finding: inability to void ii. causes include trauma to the bladder or its nerve supply during surgery, edema around bladder neck; reflex spasm due to drugs; spinal or epidural anesthesia iii. interventions encourage ambulation run water so client can hear sound pour warm water over perineum warm bath catheterization if indicated 
